What color is Mycobacterium Phlei?
phlei is a rod-shaped bacterium 1.0 to 2.0 micrometers in length. If grown on an agar plate, M. phlei colonies appear orange to yellow in color, and predominantly dense with smooth edges, although some smaller filamentous colonies have also been described.
Is Mycobacterium Phlei aerobic or anaerobic?
phlei, M . gordonae and M. kansasi in aerobic conditions only. Anaerobic cultures of both slowly and rapidly growing mycobacteria were sensitive to malachite green.
Is Mycobacterium smegmatis spore forming?
In addition, Mycobacterium smegmatis requires a unique fatty acid biosynthesis to produce the mycolic acids that are present on the cell wall. Mycobacterium smegmatis has no motility and no formation of endospores (3, 13, 14).
What does Mycobacterium smegmatis look like?
Mycobacterium smegmatis is an acid-fast bacterial species in the phylum Actinobacteria and the genus Mycobacterium. It is 3.0 to 5.0 µm long with a bacillus shape and can be stained by Ziehl–Neelsen method and the auramine-rhodamine fluorescent method.
What disease does Mycobacterium Phlei cause?
phlei) is known to be a non-pathogenic nontuberculous mycobacterium (NTM) which rarely causes diseases in humans. A disseminated NTM infection is mostly caused by the Mycobacterium avium complex (MAC) and is known to develop in immunocompromised hosts, like those with acquired immune deficiency syndrome (AIDS).
What are symptoms of Mycobacterium?
Summary
- Cough.
- Weight loss.
- Coughing up blood or mucus.
- Weakness or fatigue.
- Fever and chills.
- Night sweats.
- Lack of appetite and weight loss.
What is Mycobacterium smegmatis used for?
M. smegmatis is useful for the research analysis of other Mycobacteria species in laboratory experiments. M. smegmatis is commonly used in work on the Mycobacterium genus due to it being a “fast grower” and non-pathogenic.
What is the GC content of Mycobacterium phlei?
M. phlei has an unusually high GC-content of 73%. M. phlei is a rod-shaped bacterium 1.0 to 2.0 micrometers in length. If grown on an agar plate, M. phlei colonies appear orange to yellow in color, and predominantly dense with smooth edges, although some smaller filamentous colonies have also been described.
Is the mycolicibacterium phlei a pathogenic organism?
phlei) is known to be a non-pathogenic nontuberculous mycobacterium (NTM) which rarely causes diseases in humans. A disseminated NTM infection is mostly caused by the Mycobacterium avium complex (MAC) and is known to develop in immunocompromised hosts, like those with acquired immune deficiency syndrome (AIDS).
Which is the fastest growing mycobacteria in the world?
It is characterized as one of the fast-growing mycobacteria. M. phlei has only occasionally been isolated in human infections, and patients infected with M. phlei generally respond well to anti-mycobacterial therapy. M. phlei has an unusually high GC-content of 73%. M. phlei is a rod-shaped bacterium 1.0 to 2.0 micrometers in length.
How are the cocci of Streptococcus pneumoniae arranged?
The cocci are arranged in pairs. Examples: Streptococcus pneumoniae, Moraxella catarrhalis, Neisseria gonorrhoeae, etc. 2. Streptococci The cocci are arranged in chains, as the cells divide in one plane. 3. Tetrads The cocci are arranged in packets of four cells, as the cells divide in two plains. 4. Sarcinae
